An autopsy planned for human remains discovered in a northeast Edmonton alley was delayed Thursday and police don't expect to get results until Friday.

A human head was discovered just before 7 a.m. Wednesday, after police were called to the area of 72 Street and 131 A Avenue where it was reported that human remains were found in an alley at that address.

CTV News has learned the head is linked to a homicide near Ranfurly, Alta., approximately 137 kilometres east of Edmonton, where a dead body was found on Saturday night.

A passerby driving on Range Road 121 northeast of Ranfurly noticed an empty pickup truck parked by the side of the road wit the engine running. The passerby discovered a lifeless body lying in the nearby ditch and contacted RCMP.

RCMP said the person died as a result of a homicide, but did not release cause of death or gender of the victim.

RCMP ask anyone with information to call 780-853-4111 or Crime Stoppers at 1-800-222-8277.

Meanwhile Edmonton police are asking anyone with information to call 780-423-4567.
